Intermediate metal conduit (IMC) is a steel tubing heavier than EMT but lighter than RMC. It may be threaded. Electrical metallic tubing (EMT), sometimes called thin-wall, is commonly used instead of galvanized rigid conduit (GRC), as it is less costly and lighter than GRC. EMT itself is not threaded, but can be used with threaded fittings that ...
A three phase electric circuit terminated with a pothead Crossarms with two three phase electric circuits terminated with potheads. A pothead is a type of insulated electrical terminal used for transitioning between overhead line and underground high-voltage cable or for connecting overhead wiring to equipment like transformers.

5000 ampere copper and 4000 A aluminium bus ducts. In electric power distribution, a bus duct (also called busway) typically uses sheet metal, welded metal [1] or cast resin to contain and isolate copper or aluminium busbars for the purpose of conducting a substantial current of electricity.
A typical one-line diagram with annotated power flows. Red boxes represent circuit breakers, grey lines represent three-phase bus and interconnecting conductors, the orange circle represents an electric generator, the green spiral is an inductor, and the three overlapping blue circles represent a double-wound transformer with a tertiary winding.
The template takes a single optional parameter—a description of what the image should illustrate. Adds page to Category:Wikipedia requested electrical diagrams . If you are requesting a technical illustration (e.g. a graph), please provide as much reference data as possible.
Electrical panels, cables and firestops in an electrical service room at a paper mill in Ontario, Canada. Electrical panels are easily accessible junction boxes used to reroute and switch electrical services. The term is often used to refer to circuit breaker panels or fuseboxes. Local codes can specify physical clearance around the panels.
An electrical drawing is a type of technical drawing that shows information about power, lighting, and communication for an engineering or architectural project.Any electrical working drawing consists of "lines, symbols, dimensions, and notations to accurately convey an engineering's design to the workers, who install the electrical system on the job".
In the electrical wiring of buildings, a cable tray system is used to support insulated electrical cables used for power distribution, control, and communication. Cable trays are used as an alternative to open wiring or electrical conduit systems, and are commonly used for cable management in commercial and industrial construction. They are ...
